Add the water, bring it to boil, then simmer on a low heat for 10 minutes.
Meanwhile, prepare the chicken or pork cutlets. Cut off the fat and tenderise them by pounding them with a meat tenderiser. (Note 8)
Mix the flour, paprika, onion powder, garlic powder, mustard powder, white pepper and salt in a bowl.
Crack the egg into another bowl and beat.
Place the panko breadcrumbs in a third bowl.
Place each piece of chicken or pork into the flour until coated, then dunk them in the beaten egg and finally place them in the panko breadcrumbs until they are covered.

Place a frying pan on a high heat and fill with 0.5cm or ¼ inch of vegetable oil.
When the oil is hot, place the prepped meat cutlets into the pan and fry for 2 minutes on each side. (Note 9)
Place them onto a wire rack or board when done. (Note 10)
